Police, acting on an anonymous tip, discovered the three children, a 6-year-old boy and two girls, ages 4 and 5, locked inside a room at the couple’s Halifax Township home in December. Prosecutors say two of the children were close to dying of malnutrition.

While the Weyants raised the children, they were not their biological parents. Prosecutors say the children are in foster care.

The Weyants face a minimum of 10 years in prison when they are sentenced in May.
